Online Speaker and Stereo Test tool
Start with a low device volume. The test tone begins only after you press Play.
How to test your speakers safely
Lower your system volume before starting. The tool generates a sine-wave tone locally through the Web Audio API. It cannot measure sound quality or confirm physical speaker damage, but it can help identify a silent channel or incorrect stereo routing.
Frequently Asked Questions
Why can’t I hear the test tone?
Check system volume, output-device selection, browser tab mute settings and connected headphones.
Can this damage my speakers or hearing?
High volume can be uncomfortable. Start low and stop immediately if the tone is too loud.
Does the test record microphone audio?
No. The tool generates output audio and never requests microphone access.
